#2351 Indicate which settings are required/optional in `meltano config list <plugin>` Issue created by MeltyBot Migrated from GitLab: https://gitlab.com/meltano/meltano/-/issues/2395 Originally created by @DouweM on 2020-10-28 233807 --- We already show asterisks (

*

) next to required fields in the UI, based on the plugin's

settings_group_validation

property, like `tap-gitlab`'s: settings_group_validation: - ['api_url', 'groups', 'start_date'] - ['api_url', 'projects', 'start_date'] The array can contain one or more lists of setting names, each of which is a combination of settings that constitute a valid/complete configuration. In the case of

tap-gitlab

, this means that

api_url

and

start_date

are always required, and that

groups

, or

projects

, or both, but not neither, should also be set. In the UI, we only show an asterisk next to settings that are always required (so not

groups

or

projects

), but don't enable the "Save" button until at least one group matches completely. This means that it's not clear to the user what's wrong when all of the apparently required fields are filled in, while the "Save" button is still disabled, but this hasn't caused an issue yet because it's usually clear to users that they have to pick a specific group or project. In the output of

meltano config <plugin> list

, we can easily display asterisks where appropriate when there's only a single group of valid setting names, but I'm not sure yet what to do about

groups

and

projects

in the example above. meltano/meltano
